Tracking

Our tracking system combines OpenCV's native tracking algorithms with YOLO's object detection to allow for dynamic tracking of detected objects. It also allows us to mitigate redundant detections by comparing tracking results with YOLO's results to check if something detected is already being tracked.

Installation

To use tracking, we are using OpenCV 3.1.0 compiled with opencv modules, again at 3.1.0. If you had already installed OpenCV by following the instructions in the YOLO section, you will still have to follow these instructions to include the extra modules, but it should not affect YOLO's operation.

OpenCV 3.3.0
